Jio is world’s largest mobile network operater in 4G high speed network. 10cr custemurs gadering in very short period. Jio create a tsunami in mobile network and data providing market. The jio effect; That other operators are come down to customers doorsteps compleserly. The other operator shares are smashed in very very short time. But this boom is only Jio free offer announce by reliance. However jio network are not comfortable to 2G and 3G. This Only suitable for 4G only. And this network is not working is very hardly that’s reason; handset is very heat in few minutes. Low voice and low voice clearance. Some times customers faced voice call jumping. The other Network mobile no: not allowed by buisy buddy. Internet users suffering from handset hanged. Handset working very slow. This reasons my opinioniun; jio is not a vry good network. I’m not satisfied jio network.
